嵌入式小波分析，零树小波的程序，包含主程序，分解重构，以及提升程序(Embedded wavelet analysis, wavelet zero-tree program, including the main program, decomposition and reconstruction, and promotion procedures)

Reduction PAPR by SLM Technique

超声数据互相关算法用于塔机超声测距，程序简单方便可行( Application of the cross correlation analysis technique )

It s a type of codification or voice.

LTE中有效信噪比映射EESM算法程序，是不同子载波中的信噪比的拟合过程中的核心算法 (LTE EESM effective SNR mapping algorithm program, are fitting process different sub-carriers in the signal to noise ratio of the core algorithm)

产生M序列并求其自相关，以及矩形成形和SA函数成形时的自相关(M sequency)

说明：  用MATLAB编写的，用人口迁移算法求函数的最大值。可运行。(Prepared using MATLAB, with population migration algorithm for the maximum value function. Can run.)

In this code I have used GA in supervised PCA to find the best coeficients for overall covariance. the classification is made by KNN
